How Does A Furnace Work?

Posted On: September 23, 2022

Your HVAC system is very valuable to you. Your furnace keeps you warm and cozy on the coldest days. You and your family would likely miss your furnace very much if you didn’t have it. However, do you know how your furnace works? This may not seem relevant. After all, the only one that should work on your furnace is an HVAC technician who is trained to do so. However, it can’t hurt to know a thing or two.

Why Should You Know How A Furnace Works?

Well, knowing how your furnace works will allow you to know when it isn’t working. Most homeowners call an HVAC technician for furnace repairs when it is much too late, and the problem has worsened. If you know that something is wrong with your furnace, you can call for furnace repairs sooner, rather than later. In addition to that, you will be more familiar with furnace maintenance. It will be easier for you to take care of your furnace.

How Does A Furnace Work?

A furnace works with a series of heating cycles. A heating cycle starts as soon as the thermostat detects a change in your indoor temperature compared to its temperature setting. The thermostat then alerts your furnace to start a heating cycle. 

For gas and oil furnaces, there is a pilot or hot surface ignition to kickstart the furnace to produce heat. In an electric furnace, heating coils are used for this. This takes place in a combustion chamber. Air moves across this area and absorbs heat. This part of your furnace must get cleaned during furnace maintenance.

From here, a motor pushes the hot air from the burners to the heat exchanger. A heat exchanger holds the heat and then transfers it to your ductwork. A blower motor will push the air through your ducts and vents and eventually enters your home. 

Once the cycle ends, your thermostat will signal that the temperature in your home is the same as its set temperature. It will then cause your furnace to shut down until the temperature drops again.

Before the air travels back through your furnace, it goes through an air filter. Air filters prevent dust and dirt from getting into the furnace. This is an important safety feature. Air filters should be changed every 3 months or more often.

Now that you know a bit more about your furnace, you can keep your eye out for potential issues. While you may know the basics of how a furnace works, it is a complicated HVAC system.
